Rand KR-3


The KR-3 amphibian was originally designed and built by Ken Rand and Stu Robinson in 1976. The prototype was first tested in June 1977. Follow-ing Ken’s tragic death in a plane crash, the improved prototype was completed in February 1981, and was undergoing FAA certification as an Amateur-Built air-craft.


The KR-3’s wings are removable and the aircraft is trailerable. The new fuselage is 9” longer than the original, with the C of G moved forward 8” and the airfoil changed from GA(W)-1 to basically a Clark Y 4418 tapering to 4412. Following the trend-setting construction techniques of the KR-1 and KR-2, the KR-3 amphibian is quick and easy to build from wood, foam, Dynel and epoxy resin. The engine is a 2100cc Rev-master VW conversion with a three bladed Rand-Robinson propeller. The tricycle gear is hydraulically actuated. Retraction and extension are a matter of flipping a micro switch to the appropriate position and pumping a light handle located between pilot and passenger. Turbocharging permits the KR-3 to operate efficiently at altitudes up to 15,000 feet.
